Hi Lori----
I would certainly like to see the author(s) of the information you read prove that one!! Since analysis has shown that the green-colored stones are from bile, and the tan colored are cholesterol/fats (and not the unsaturated fats of olive oil), I'd like to know what it is in the body they think is providing this "alchemistic transformation".
I've also read of individuals that proclaim the stones as soap/soapstone, and would like to see where in the body that process can occur. If you read about soap-making, you'll see that the fat(s) need to be boiling when the lye is added, in order to make them bond and solidify. If my memory serves me correctly, this process is called saponification.
If you do the series of four cleanses, your health will improve dramatically....and it won't pay for anyone's BMW except yours!!
